SUMMARY
Angle of twist and degrees of rotation are distinct concepts in beam mechanics. The angle of twist, calculated using the formula TL/JG, represents the rotation around the beam's centroidal axis due to torsion and is measured in radians. In contrast, degrees of rotation, derived from the moment equation EI dw/dx, indicates the beam's deflection from the horizontal and is unit-less, expressed in degrees. Understanding the difference between these two measurements is crucial for accurate analysis in structural engineering.
